BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 489,637, dated January 10, 1893.

Application filed May 27, 1892. serial No. 434,660. (No model.)

To all whom it may concern.-

Be it known that I, FRANZ LUDWIG VON HIRSCH, a subject of the German Emperor, residing at Dusseldorf, in Germany, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

This invention relates to a bottle-stopper which discharges the contents of the bottle in drops and is designed for medicinal, chemical or similar uses.

It consists in the various features of improvement more fully pointed out in the claim.

In the accompanying drawings: Figure 1 is an elevation of a bottle provided with my improved stopper. Fig. 2 a similar view showing the bottle inclined and Fig. 3 a vertical central section of Fig. 1, without the plug it.

The letter (1, represents a bottle stopper adapted to fit into the neck of a bottle A, and provided on top with a mortise a, for the reception of an additional stopper, cap or plug 7c. The stopper a, is provided with two vertical perforations through which extend two tubes 0, cl, of unequal length, the tube cl, projecting farther into the bottle than the tube 0. The longer tube d, may also be somewhat wider than the shorter tube a. When the bottle is inclined (Fig. 2) a larger column of liquid will press upon the shorter, than upon the longer tube. This will cause air to enter through the longer tube d, and liquid to be discharged through the shorter tube 0. The diameter of this shorter tube is such, that it gives off its charge in drops. The object of the stopper 7a, is to close the tubes 0, d, when the bottle is put away.

What I claim is:

The combination of a bottle with a perforated stopper having mortise a, a pair of tubes of unequal length projecting through the stopper into the bottle and with a plug 70, adapted to be received by the mortise, substantially as specified.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
